Dynamic behaviour of foams. Foam flow occurs in many industrial processes such as the fractionation of proteins and coal flotation. The proposed research will investigate transient behaviour at start-up of such processes and how the method of foam production affects process efficiency. The dispersion of liquid tracers in foam and a newly discovered phenomenon of ?upwards rippling? will be studied as it is likely that these could illuminate the physical processes that lay behind foam flow.

The proposed research will investigate transient behaviour at start-up of such processes and how the method of foam production affects process efficiency. The dispersion of liquid tracers in foam and a newly discovered phenomenon of ?upwards rippling? will be studied as it is likely that these could illuminate the physical processes that lay behind foam flow. Removal of unwanted material from a pipeline is often a major industrial problem and the ability of foams to perform this role will be assessed.Read moreRead less
